XIAOMI(HK:01810) Sou Hu Cai Jing·2026-01-05 02:43Core Viewpoint - Xiaomi's chairman Lei Jun addressed recent controversies regarding the company's automotive safety design, emphasizing that the "wheel detachment" concept is a well-established safety design principle in luxury brands, originally proposed by Mercedes-Benz [1][3]. Group 1: Historical Context - The "wheel detachment" safety concept can be traced back to the 1950s, with Mercedes-Benz safety engineer Béla Barényi being the first to propose modern passive safety principles, including crumple zones and "force transfer paths" [3]. - The first implementation of this concept was in the 1959 Mercedes-Benz W111 model, marking the inception of the "wheel detachment for vehicle protection" safety logic [3]. Group 2: Design Philosophy - The design is not intended to allow wheels to "fly off" but aims to dissipate impact energy in extreme collision scenarios by sacrificing non-critical components like wheels and suspension, thereby maximizing occupant safety [3]. - Other brands such as Volvo, BMW, and Audi have adopted and optimized similar structural designs, making it a common practice in automotive safety engineering [3]. Group 3: Xiaomi's Commitment - During a recent live stream of the Xiaomi YU7 teardown, viewers could clearly see the structural design details, showcasing Xiaomi's significant investment in automotive safety [5]. - The company has established safety as a foundational principle from the outset of its vehicle development process [5].
